DESCRIPCIONDESCRIPTION
Estructura soporte para colector solar cilindro parabolico descompuesto.Support structure for solar collector decomposed parabolic cylinder.
La presente invention se refiere a la Estructura Soporte para Colector Cilindro Parabolico Descompuesto (CCPD), para la concentration de la radiation solar, gracias a la cual se consiguen minimizar los costos de fabrication y montaje de los CCPD.The present invention relates to the Support Structure for Decomposed Parabolic Cylinder Manifold (CCPD), for the concentration of solar radiation, thanks to which the manufacturing and assembly costs of the CCPD are minimized.
Antecedentes de la invencionBackground of the invention
El Colector Cilindro Parabolico Descompuesto consta de un diseno de tramos de parabolas de diferentes relaciones geometricas, distintas distancias focales, en las que se hacen coincidir sus puntos focales, dicha configuration se realiza para crear un camino libre en el seno del captador para que circule el viento incidente sobre este, asl el viento no queda atrapado, y transfiere en menor medida las cargas a la estructura, imprimiendo menores vibraciones en esta.The Decomposed Parabolic Cylinder Manifold consists of a design of parabola sections of different geometric relationships, different focal distances, in which their focal points are matched, said configuration is made to create a free path within the collector to circulate the wind incident on this, asl the wind is not trapped, and transfers the loads to the structure to a lesser extent, printing minor vibrations on it.
Son conocidas las descomposiciones de las geometrlas parabolicas continuas de captadores solares, como se puede apreciar en la patente: US 2010205963 A1 (AMMAR DANNY F) 19.08.2010, en la que descompone la geometrla parabolica continua en tramos, que generan sectores rectangulares, en vez de un unico cuerpo cillndrico de seccion parabolica, los cuales estan caracterizados por la longitud de la seccion del rectangulo, la cual es a lo sumo dos veces el diametro del tubo absorbedor, que se situa en el foco, dichos rectangulos se conforman con una pequena curvatura y se disponen espaciados entre ellos y enfocados al absorbedor, concentrando asl la radiacion solar directa.The decompositions of the continuous parabolic geometries of solar collectors are known, as can be seen in the patent: US 2010205963 A1 (AMMAR DANNY F) 19.08.2010, in which it decomposes the continuous parabolic geometry in sections, which generate rectangular sectors, in instead of a single cylindrical body of parabolic section, which are characterized by the length of the section of the rectangle, which is at most twice the diameter of the absorber tube, which is located in the focus, said rectangles conform to a small curvature and are arranged spaced between them and focused on the absorber, thus concentrating direct solar radiation.
Otra descomposicion de parabolas de mayor peso tecnologico se puede observar en la patente: US 2011 / 0214666 A1 (CHRISTOPH PRAHL) 17.11.2009. Foreing Application Priority Data Nov 18.2088 (DE) 102008057868.1, para una apertura de parabola de doce metros. Habiendose realizado un estudio a fondo mediante el metodo de elementos finitos, sobre esta descomposicion, por parte de los senores/as Christoph Prahl, Tamara Schapitz, Ralf Uhlig (Plataforma Solar de Almerla), titulado: Optimierung der Struktur eines linienfokussierenden kollektors mit ortsfestem Absorber. En dicho analisis de fluidomecanica computarizada mediante el metodo de elementos finitos, se implementa un modulo de doce metros de largo y seis metros de apertura de parabola, obteniendose los resultados de las incidencias de las cargas de viento sobre la estructura parabolica descompuesta y su estructura soporte. Dicha estructura soporte se desarrolla en el seno de la parabola para poder soportar a los espejos "S2" (segun denomination propia de la patente), y que realiza un seguimiento solar en un eje girando sobre su foco. Hay que tener en cuenta que dicha estructura soporte imprime unas perdidas por sombreamiento en la captation de la radicacion solar directa.Another decomposition of parabolas of greater technological weight can be observed in the patent: US 2011/0214666 A1 (CHRISTOPH PRAHL) 17.11.2009. Foreing Application Priority Data Nov. 18.2088 (DE) 102008057868.1, for a parabola opening of twelve meters. Having conducted an in-depth study using the finite element method, on this decomposition, by Messrs. Christoph Prahl, Tamara Schapitz, Ralf Uhlig (Solar Platform of Almerla), entitled: Optimierung der Struktur eines linienfokussierenden kollektors mit ortsfestem Absorber . In said analysis of computerized fluidomechanics using the finite element method, a module of twelve meters long and six meters of parabola opening is implemented, obtaining the results of the incidences of wind loads on the decomposed parabolic structure and its support structure . Said support structure is developed inside the parabola to be able to support the mirrors "S2" (according to the patent's own denomination), and which carries out solar tracking on an axis rotating on its focus. It must be taken into account that said support structure prints some losses due to shading in the captation of direct solar radiation.
Por ultimo mencionar la solicitud de patente nacional: 201200911 (ANTONIO VARGAS) 10.09.2012 COLECTOR SOLAR CILINDRO PARABOLICO DESCOMPUESTO. La cual esta caracterizada por desarrollar una descomposicion del captador mediante dos desarrollos parabolicos de distinta distancia focal, una de cuatrocientos millmetros y otra de seiscientos millmetros.Finally mention the national patent application: 201200911 (ANTONIO VARGAS) 10.09.2012 SOLAR COLLECTOR PARABOLIC CYLINDER DECOMPOSED. Which is characterized by developing a decomposition of the sensor through two parabolic developments of different focal length, one of four hundred millimeters and another of six hundred millimeters.

No obstante, todos estos modelos de descomposicion de las secciones de las parabolas quedan a nivel teorico, y no llegan a desarrollarse industrialmente. Siendo esta el estado de la tecnica actual.However, all these models of decomposition of the parabola sections remain at the theoretical level, and do not develop industrially. This is the current state of the art.
En consecuencia, se ha ideado una nueva Estructura Soporte para Colector Cilindro Parabolico Descompuesto, partiendo de la descomposicion de las parabolas de Antonio Vargas, siendo esta una solucion optima de compromiso entre maxima apertura desarrollada en torno dos metros y minima area de perdidas de captation por descomposicion para tramos de espejos de misma geometrla en plano antes de plegar. Minimizando los costos de fabrication y montaje, cuyas caracterlsticas son el objeto de la presente invencion.Consequently, a new Support Structure for Decomposed Parabolic Cylinder Collector has been devised, based on the decomposition of the parables of Antonio Vargas, this being an optimal compromise solution between maximum opening developed around two meters and minimum area of captation losses by decomposition for sections of mirrors of the same geometry in plane before folding. Minimizing manufacturing and assembly costs, whose characteristics are the object of the present invention.
Description de la inventionDescription of the invention
La nueva Estructura Soporte para Captadores Cilindro Parabolicos Descompuestos consta de un eje estructural, sobre el cual se fijan las estructuras soportes de los espejos de secciones de tramos parabolicos.The new Support Structure for Decomposed Parabolic Cylinder Collectors consists of a structural axis, on which the support structures of the parabolic section section mirrors are fixed.
Dicho eje estructural, esta dotado de una manivela para conectar distintos ejes mediante bielas y as! poder realizar el seguimiento solar de varios captadores mediante un unico actuador.Said structural axis, is equipped with a crank to connect different axes by connecting rods and ace! to be able to carry out the solar tracking of several sensors through a single actuator.
Sobre el propio eje descansan los apoyos de los soportes donde se fijara el tubo absorbedor, que se situara en el foco de las parabolas de distintas distancias focales que se han hecho coincidir.On the same axis rest the supports of the supports where the absorber tube will be fixed, which will be located in the focus of the parabolas of different focal distances that have been made to coincide.
El soporte de los espejos se realiza mediante una celosla plana y se fija sobre el eje estructural, pudiendose arriostrar los soportes entre si, para que los espejos no tengan que soportar ningun tipo de carga.The support of the mirrors is carried out by means of a flat lattice and is fixed on the structural axis, the supports being able to brac each other, so that the mirrors do not have to support any type of load.
Una de las caracterlstica principales de la nueva estructura, es que en su despiece se compone de elementos planos, lo que ayuda a su apilamiento y minimiza los costos de transporte.One of the main characteristics of the new structure is that in its exploded view it is made up of flat elements, which helps in its stacking and minimizes transport costs.
Al tratarse de estructuras planas prefabricadas, el ensamblaje en campo resulta sencillo debido a que solo ha de atornillarse los cuerpos principales del conjunto y ensamblar los espejos.Being prefabricated flat structures, field assembly is simple because only the main bodies of the assembly have to be screwed and the mirrors assembled.
Se ha determinado una solucion optima en la descomposicion de las parabolas que acota la geometrla de la estructura para adecuarse a tres espejos planos rectangulares de mismas dimensiones geometricas que se curvan de la siguiente forma:An optimal solution has been determined in the decomposition of the parabolas that delimits the geometry of the structure to adapt to three rectangular flat mirrors of the same geometric dimensions that are curved as follows:
- Un espejo central simetrico que describe una curva parabolica con una distancia focal de cuatrocientos millmetros.- A symmetric central mirror that describes a parabolic curve with a focal length of four hundred millimeters.
- Dos espejos laterales que describen un tramo de parabola con una distancia focal de seiscientos millmetros.- Two side mirrors that describe a parabola section with a focal length of six hundred millimeters.
Esta configuration de los espejos parabolicos permite introducir una estructura triangulada en el lugar geometrico de los puntos que describirlan la parabola exterior, que rigidiza la estructura y consiguen disminuir la altura neta de construction del captador enThis configuration of the parabolic mirrors allows to introduce a triangulated structure in the geometric place of the points that will describe the outer parabola, which stiffens the structure and manage to reduce the net construction height of the sensor in

comparativa a una geometrla de parabola continua, consiguiendo un captador parabolico con menor altura geometrica desarrollada por las geometrlas de los espejos.Compared to a continuous parabola geometry, obtaining a parabolic sensor with a lower geometric height developed by the mirror geometries.
En una realization opcional, la estructura puede llevar como anexo un tubo absorbedor de vaclo de agua caliente sanitaria, cuya longitud media comercial es de dos metros, lo que nos acota la longitud de los espejos de tramos cilindro parabolicos a soportar por la estructura objeto de la presente invention.In an optional realization, the structure may have as an annex a sanitary hot water vacuum absorber tube, whose commercial average length is two meters, which limits the length of the parabolic cylinder section mirrors to be supported by the structure object of The present invention.
El angulo de instalacion entre la horizontal y el eje estructural del conjunto objeto de la invencion que estamos describiendo se realizara de acuerdo al punto de diseno de cada instalacion, dependiendo de la naturaleza de la demanda de energla termica que se le exige al CCPD, dicha condition nos determinara las longitudes exactas de los soportes delanteros y traseros de la estructura objeto de la presente invencion.The installation angle between the horizontal and the structural axis of the set object of the invention that we are describing will be made according to the design point of each installation, depending on the nature of the demand for thermal energy that is required of the CCPD, said condition will determine the exact lengths of the front and rear supports of the structure object of the present invention.

Descripcion de una realizacion preferidaDescription of a preferred embodiment
Para lograr un mayor comprension de la invention, a continuation, se va a describir la Estructura Soporte para Colector Cilindro Parabolico Descompuesto, segun una realizacion preferente.In order to achieve a better understanding of the invention, the Support Structure for Decomposed Parabolic Cylinder Manifold will be described below, according to a preferred embodiment.
En las figuras 1-4 se observa una realizacion preferente de la estructura Soporte para Colector Cilindro Parabolico Descompuesto en la que el eje estructural (8) es de section cuadrada cuya alineacion con el vertice y el foco de las parabolas se realiza por dos de sus vertices opuestos (quedando en visualization romboide). De esta forma, quedan las dos caras superiores del rombo disponibles para fijar las estructuras soportes de los espejos (5), (figura 2, 3).In Figures 1-4 a preferred embodiment of the Support structure for Decomposed Parabolic Cylinder Manifold is observed in which the structural axis (8) is of square section whose alignment with the vertex and the focus of the parabolas is made by two of its opposite vertices (remaining in rhomboid visualization). In this way, the two upper faces of the rhombus are available to fix the support structures of the mirrors (5), (figure 2, 3).
Para una correcta fijacion de las celoslas planas soporte de los espejos (5), y para dar rigidez a la propia estructura, se opta por dotar a los soportes de los espejos (5) de unas cruces de San Andres, las cuales de desarrollan en el lugar geometrico de los puntos que describen la parabola de mayor distancia focal (2, 4), siendo posible esto gracias al uso de la filosofla de descomposicion de las parabolas que comparten un mismo foco (figura 4).For a correct fixation of the flat cellolas, support of the mirrors (5), and to give rigidity to the structure itself, it is decided to provide the supports of the mirrors (5) with some crosses of San Andres, which are developed in the geometric place of the points that describe the parabola with greater focal length (2, 4), this being possible thanks to the use of the decomposition philosopher of the parabolas that share the same focus (figure 4).
La cruz de San Andres anteriormente descrita, se caracteriza por describir un angulo de noventa grados en su cruz, geometrla que se acopla con las dos caras superiores del rombo que describe el perfil cuadrado del eje estructural (8). Para crear una buena fijacion atornillada o remachada entre el soporte de los espejos y el eje estructural, se opta por dotar a la cruz de San Andres, en su union con el eje estructural (8), de un perfil "L” en la direction del eje estructural, con la finalidad de aumentar el area de contacto y espaciamiento entre elementos de union.). Sobre los extremos del eje estructural (8) se colocaran los elementos que permitan el giro del captador.The San Andres cross described above is characterized by describing a ninety degree angle at its cross, a geometry that is coupled with the two upper faces of the rhombus that describes the square profile of the structural axis (8). To create a good fastening screwed or riveted between the support of the mirrors and the structural axis, it is decided to provide the cross of San Andres, in its union with the structural axis (8), of a profile "L" in the direction of the structural axis, in order to increase the area of contact and spacing between joining elements.) On the ends of the structural axis (8) the elements that allow the rotation of the sensor will be placed.
Como se puede observar en las figuras, la soportacion del tubo absorbedor (11) se realiza mediante dos perfiles (6, 7) que arrancan directamente del eje estructural (8).As can be seen in the figures, the support of the absorber tube (11) is carried out by means of two profiles (6, 7) that start directly from the structural axis (8).
Otra caracterlstica esencial de la estructura es que se compone de elementos planos y de rapido ensamblaje que minimizan los costos de fabrication, transporte y montaje en campo.Another essential feature of the structure is that it consists of flat elements and quick assembly that minimize manufacturing, transportation and field assembly costs.
Los espejos (2, 3, 4) dispondran de unas correas de atado en los puntos de union a la estructura (5) que uniran las distintas estructuras soportes de espejos (5) de un mismo captador, en la direccion del eje estructural (8), cuyo objetivo es liberar al espejo de cualquier tipo de carga, quedando estas correas por el lado posterior al espejado.The mirrors (2, 3, 4) will have straps tied at the points of attachment to the structure (5) that will join the different support structures of mirrors (5) of the same sensor, in the direction of the structural axis (8 ), whose objective is to free the mirror of any type of load, leaving these straps on the back side of the mirror.
Otra caracterlstica esencial de la estructura es que esta dotada de una manivela (9), la cual enlaza mediante bielas las distintas estructuras que compongan el campo solar, y mediante el acople de un unico actuador en la manivela (10), poder gobernar el seguimiento solar de todos los captadores mediante el conjunto de bielas y manivelas que describiran una movimiento de cuatro barras.Another essential characteristic of the structure is that it is equipped with a crank (9), which links the different structures that make up the solar field by connecting rods, and by coupling a single actuator on the crank (10), to be able to govern the monitoring solar of all the sensors by means of the set of connecting rods and cranks that will describe a movement of four bars.
